Order Minimum and Maximum rules are set by Brand Admins to specify rules for buyers when placing orders on NuOrder. As an Admin user, you can enable these specifications by going into Brand Admin> Settings> Order Min Max Rules.
From here, you have the option to select which type of rule you wish to create and at which level. My example below shows a rule that is currently set up at the Size level, that restricts users from ordering any less than 4 quantities per size for the style number "1002".
